BURT, OFROCHESTER, NEW YORK MEANS AND METHOD FOR FORMING SOFT-METAL BARSApplication filed February 7, 1929. Serial No. 338,100.

My invention relates broadly to the art of extruding metal throughforming dies and more particularly to extruding molten metal, such astype metal through forming dies,

wherein it is cooled or solidified, to form continuous leads, rules andthe like, which are cut, as they emerge from the dies, intopredetermined lengths to be used by printers.

The principal object of my invention is to provide a means and method ofproducing metal bars, such as printers leads, rules and the like, inlarge'quantities and so cheaply that printing otfices, which heretoforehave been limited to the use of commercial leads and rules, may, bymeans of my invention, make their own of the size and form best suitedto their needs, and so cheaply that the leads and rules need not beseparated from the used type to be used again, but will be remelted withthe type and re-cast with my machine, this being cheaper than saving theold leads.

Other objects of my invention relate to means for melting and extrudingthe metal,

the dies for forming leads and rules of various sizes in the samemachine, means for cutting and discharging the bars from the machine,and means for adjusting and synchronizing all of the parts to form anefiicient and compact machine.

Still other objects and advantages of my invention will be apparent tothose skilled in the art, as the specification proceeds, and need not bespecifically pointed out.

With the above and other objects in view, reference will now be had tothe accompanying drawings wherein a preferred embodiment of myinvention'is illustrated.

Referring to Fig. 2, the cylinder 25 is submerged in the molten metal 26Within the reservoir or melting pot 27 the cylinder having a flange 28at one end bearing on the head 29 while the other end of the cylinder isthreaded to receive the nut 30 which bears against the other head 31 ofthe melting pot. Molten metal enters the cylinder through the valve 32(Fig. 7) when the plunger or ram 33 (Fig. 2) makes its return-stroke,the valve 32 then seating because it is made of material, such as steel,that is of less specific gravity than the molten metal. On the forwardor working stroke of the plunger, the molten.

metal is forced through the die or nozzle 34,

which is water jacketed so that the metal solidifies while beingextruded in the form of a bar 35 on the delivery table 36. When the ram33 reaches the end of its working stroke and starts again on its nextreturnstroke, a circular cut-ofl' saw 37 is raised by mechanismpresently to be described and cuts off the bar 35 adjacent the die 34.

The ram 33 extends beyond the cylinder 25 and is enlarged at its rearend and screw threaded at 38 to engage a correspondingly threaded nut 39secured to the worm wheel 40 and bearing on the thrust bearing 41 whichis supported by the head 42. Tie rods43 connect the head 42 to the head31 of the melting pot and take up the thrust on the ram 33. The wormwheel 40 is driven in one direction to advance the ram 33 and reversedto withdraw it by mechanism presently to be described,

A shaft 44, driven by a reversible electric motor or other suitablesource of power, carries a worm 45 which meshes with and drives the wormwheel 40 and also with a worm wheel 46 for driving the cut-off ,and.delivery shaft 47. The worm wheel 45 and nut 39 are rotated in oppositedirections by the shaft 44 to advance and withdraw the plunger 33, but

the cut-oif'shaft 47 is rotated only in one di-- rection and thatintermittently and in timed relation to the plunger stroke, by clutchmechanism best shown in Figs. 10 and 13 The movements of the plunger orram 33 are controlled by mechanism best shown in Figs. 3, 5, 6, 11 and12. The frame of the machine that houses the driving mechanism has a topplate or cover 47 provided with a slot 48 extending parallel to theplunger and somewhat longer than its greatest working stroke. A slide 49within this slot has a limited movement in opposite directions, and atone end has an adjustable stop 50, while its other end has a pair oflugs 51, 51, adapted to throw the reversing switch 52 in oppositedirections to reverse the motor, or other means for driving the shaft44, at each end of the plunger stroke.

A reversing yoke 53 travels with the plunger 33, sliding on the uppertie rod 43, and has a finger 54 operating in the slot of the slide 49,as best shown in Fig. 6. The finger 54 engages the slide 49 at one end,(at the end of the. outstroke of the plunger), and actuates thereversing switch 52 to reverse the motor, or tither driving means, tocause the plunger 33 to advance in the cylinder and .extrude through thedies the metal that now fills the cylinder. The adjustable stop 50 isset at such a point in the slot of the slide 49, that it will be engagedby the finger 54 and move the slide 49 to again reverse the switch 52when the plunger or ram has moved far enough to have extruded sulficientmetal to form a rule of the desired length. This causes the ram to beagain retracted and the operation is repeated. The length of the ramtravel is controlled byt-he position of the stop 50, and the length ofthe lead or rule will depend not only on the length of the stroke of theram but also on the .cross-sectional area of the forming die. Thus witha given plunger stroke, a much longer lead will be produced with a dieas shown in Fig. 21 than with the larger die shown in Fig. 20.Conversely, if leads or rules of the same length are wanted, the plungerstroke will be longer when using the dies of Fig. 20 than when using thedies of Fig. 21 or 22.

The mechanism for operating the cut-ofi Referring first to Fig. 10, thesleeve 55 fixed in the head 42 provides bearings for the worm wheel 46and shaft 47. The wheel 46 is secured to one part 56 of a one-way ballclutch 57. See Fig. 13. When the plunger is advancing on its workingstroke, this clutch is inoperative, the outer member 57 being stationaryand the inner member running idly. When the drive shaft 44 is reversedto retract the plunger, the clutch 57 rotates idly on the inner sleeve58 of a trip clutch, which is automatically controlled to drive theshaft 47 through one rotation, thereby raising the saw 37 to cut off thelead (Fig. 9) and again returning the saw to inoperative position (Fig.8) I When the lead or rule has been cut off, the delivery plungers 59,Fig. 2, are actuated by the levers 60 to press the lead or rule to oneside on the delivery table 36, out of the path of the next lead to beextruded.

The clutch 58 is of the type generally known as a punch-press clutch,and while the outer sleeve 57 (the one sleeve 57 is common to bothclutches. See Fig. 10) is driven continuously during the interval thatthe ram is being retracted, the member 58 and shaft 47 make but onerotation and then stop.

The collar 58 is fixed to the shaft 47 and has a sleeve 61 fittingwithin the clutch member 57. A clutch finger 62 fits in a circular bore63 in the collar 58, and has a semi-circular extension .64 which lieswithin a semicircular recess 65 formed in the sleeve 61, coaxial withthe bore 63.

The collar 57 has a corresponding semi-circular recess 66, adapted toregister at times with the recess 65. (See Figs. 14 to 17, Sheets 1 and5.) When the finger 62 is in such po sition that the extension 64 lieswholly within the recess 65, the clutch runs idly, and the shaft 47 isnot rotated. (See Fig. 17 But when the extension 64 lies artly withineach recess 65, 66, the shaft 4 will be rotated (.Fig. 15).

The operation of this clutch will now be described. .The finger 62 as acurved lateral extension 67, (Figs. 6, 18, 19) which is urged outwardlyby the spring 68, tending to cause I the upper end 'of lever 74 isreleased.

the semi-circular part 64 to lie within both recesses 65, 66, as in Fi15. The collar 58 has a recess 69 within w ich the extension 67 ispartly housed when depressed against the spring 68 (Fig. 6). A lowertrip lever. 70, pivoted at 71, (Fig. 6) has a notch 72 in its lower endwhich normally engages the extension 67 and depresses it into the recess69 so that the trip clutch is inoperative. A spring 73 tends to hold thetrip lever in this position. An upper trip lever 74 also is pivoted at71 and at its lower end has a finger 75 engaging lever 70. A spring 76pulls on the upper end of lever 74 and is stronger than the spring 73,so that the lever 70 will be disengaged from the trip finger extension67, whenever See Figs. 1, 3, 5 and 6.) A clutch control liever 77 ispivoted at 78 at one end and at the other end is adapted to engage theupper end of the lever 74 against the tension of the spring 76. A lightspring 79 tends to pull the control lever 77 to one side to release thelever 74 (see Fig. 5), and a cam 80 on the oke 53 engages a roller 81 topress the lever 7 back into engagement with the lever 74 at the propertime.

The slide 49 carries a laterally projecting foot 82, extending into thepath of the upper end of the lever 74, and is adapted, as the slide ismoved to the right (Figs. 1, 3 and 5) at the end of the piston stroke,to engage the upper end of lever 74 and move it against the pull of thespring 7 6. 1

The operation of the clutch mechanism for driving the shaft 47 is asfollows. When the ram 33 is being forced forwardly to extrude the metal,the clutch member 56 runs idly, the outer member 57 being stationary, sothat the trip clutch 58 is inoperative regardless of the position of thelevers 7 O, 74 and finger 62. As the piston nears the end of its stroke,the finger 54 engages the adjustable stop 50 and moves the slide 49 tothe right, carrying the foot 82 with it into engagement with the lever74. Just previous to the end of the forward stroke, the positions of theclutch control levers and cams are as follows. The foot 82 is to theleft (Figs. 3 and 5) out of engagement with lever 74 which has beenpulled to theleft by spring 76 and holds the lower end of lever 70 outof engagement with clutch finger 67. The cam 80 is out of engagementwith roller 81 and control lever 77 has been pulled toward the center ofthe machine out of engagement with the upper end of upper trip lever 74.The

spring 68 has raised the clutch finger 67 higher than the notch 72 (Fig.24), so that the lever cannot return to position. The plunger nowreaches the end of its forward stroke carrying the foot 82 intoengagement with lever 74, forcing it to the right and releasing lowertrip lever 7 O, which is then drawn by the light spring 73 againstclutch finger 67 ready to move into position to receive the finger innotch 72 and confine it in recess 69 scribed, and the drive shaft nowbeing re-' versed, the clutch member 57 begins to turn, but the member58 remains stationary until the two grooves 65, 66 register, at whichtime the finger 64 engages in both grooves and causes the clutch 58 andshaft 47 to rotate. A slight rotation of the clutch 58 carries thelateral extension 67 past the lever 70, and the spring 73 pulls thelever to the left to the position shown in Figs. 3 and 10, so that asthe clutch continues to turn, the extension 67 will come under the leverand in the recess 72 and be depressed against the pressure of spring 68.This takes place when the clutch and shaft 47 have made one completerotation and turns the finger again into inoperative position as shownin Fig. 17, so

that continued rotation of the clutch 56, 57'

has no effect on shaft 47. I

The ram 33 continues on its back stroke, and near the end of its stroke,the cam 80 engages roller 81 and moves lever 77 into engagement withlever 74 as shown in Fig. 5. Continued movement of the piston, causesslide 49 to be shifted to the left carrying foot 82 to the left of lever74 and again reversing the drive shaft.

The ram now starts on another working stroke and forward movement of cam80 releases lever 77 which is pulled to one side by spring 79. Thisreleases upper trip lever 74 which is pulled over by spring 76 andcauses lever 70 to release the finger 67 which is forced up by spring68, but the shaft 47 is not driven because the clutch 56, 57 isinoperative during the Working stroke of the ram. However, the lever 70and clutch finger 62, 68, remain in this position, ready to come intooperation and drive the shaft 47 through one rotation as soon as theshaft 44 is reversed.

The cut-ofl and delivery mechanism that are actuated by shaft 47 willnow be described.

As the rules or leads 35 leave the forming dies 34, they come out on thetable 36, the stroke of the ram having been regulated by the position ofthe stop 50, so that the lead extruded will be of a predeterminedlength. When the metal has ceased to flow through the die, and the ramis being retracted, the shaft 47 is given one complete rotation, aspreviously described, which operates the cutoif and delivery mechanism.

As a rule 35 progresses along the table 36, by pressure of the metalbehind it, it is kept in alignment with the rules previously extruded bythe spring pressed retaining fingers v a lead 35 is being extruded,while in Fig. 2,

the last lead has been cut off and moved to one side by the plungers outof the path of the next lead to be extruded from the dies.

The shaft 47 has bearings in the heads 31, 29 (Figs. 3 and 10) and atits one end carries a cam 85 and crank 86. The cam 85 cooperates with aroller 87 on one end of an arm 88 which is fixed to a rock shaft 89carrying the delivery levers 60. (Figs. 8 and 9.) These :evers actuatethe plungers 59 (Figs. 2 and 4) as previously described to move thestack of leads or rules out of the path of the next following one. I

The saw 37 is secured to one end of a shaft 90 mounted in a swingingframe 91 and driven from an electric motor 92 or other source of power.The motor is eo-axial with the swinging frame 91, as best shown inFig. 1. The motor 92 is only illustrative of a driving means, and ofcourse any driving means, as a shaft driven from the main drive shaft44, could be substituted.

A downwardly and forwardly extending link 93 is pivoted at one end tothe swinging frame 91 and at the other end is mounted on the pin 94 ofthe crank 86.

It will be clear from the above description, that when the shaft 47 isrotated, the crank 86, through the curved link 93 and frame 91, willraise the saw 37 and cut off the lead. Shortly thereafter, and duringthe same revolution, the cam 85 will engage the arm 88 and oscillate thelevers 60 against the plungers 59 and push to one side the lead 35 thathas just been cut off.

Referring to Figs. 8, 9, 20, 21 and 22, it will be noted that the righthand side of the opening in the die is always the same distance from theright hand edge of the die, regardessof the dimension of the opening.This is of importance, because the plungers 59 always move just farenough so that the near side of the last lead .or-ruleis shoved justbeyond the edge of the die, so that the next lead to be formed will comeout on the delivery table close along side of the preceding one.

The nozzles or dies, previously referred togenerally by the number 34,are best shown in Figs. 1, 2, 8, 9, 20, 21 and 22, and form an importantpart of my invention. Each die is formed in two parts 95, 96 havingaccurately ground faces 97, 98 so that there will be no leakage ofcooling water from the cooling passages 99, 100, which are connected tothe pipes 101, 102 carrying cooling water or other fluid. 1

The dies are secured in place in the following manner. A plate 103,clamps 104, and a fixed jaw are secured to the head 29 of the meltingpot by means of bolts 105, (Figs. 8, 9, 23), the transmission of heat tothe plate being minimized by insulation 106. The fixed jaw 107 haspassages connecting with the cooling pipes 101, 102 and passages 99, 100in the dies. The clamps 104 engage a sliding jaw 108 which is adapted tobe adjusted by the hand screw 109 threaded in a fixed thrust block 110.Each of the jaws 107, 108 has a clamp 111, 112, adapted to engage theshoulders 113 on the dies, as best shown in Figs. 2 and 4.

The dies shown in Figs. 20 to 21, as well as all dies to be used in mymachine, are interchangeable and can easily be removed or changed. Tochange from one set of dies to another, the bolts holding the clamps111, 112 are loosened, after first having shut off the flow of coolingwater. The hand screw 109 is then turned to withdraw the sliding jaw108, after which the die 95, 96 can be lifted out. A new die is theninserted, with the open ends of the cooling passages toward the pipeconnections 101, 102. The hand screw 109 and clamps 111, 112 are thentightened and the machine is again ready for operation.

The operation of my machine is continuous and. automatic, and afterbeing set in operation continues to make leads or rules of uniformlength stacked on the delivery table, as long as the melting pot is keptsupplied with metal. In large printing shops, the machine will be keptin continuous operation, the leads and rules being taken fromthe-delivery table and used as fast as they are cut off. After beingused, the leads and type are not separated, but all are thrown into acommon melting pot, which may be the pot of this machine, and remeltedfor again casting in the form of type or leads and rules, as the casemay be.
